dnsmasq ipset 配置

	list domain '.gvt0.com'
	list domain '.gmodules.com'
	list domain '.blogger.com'

添加文件 nftables.d/20-mangle-wgset.nft

chain mangle_prerouting_wgset {
	type filter hook prerouting priority mangle; policy accept;
	ip daddr @wgset meta mark set 0x00003c85 counter accept
	ip6 daddr @wgset6 meta mark set 0x00003c86 counter accept
}

chain mangle_output_wgset {
	type route hook output priority mangle; policy accept;
	ip daddr @wgset meta mark set 0x00003c85 counter accept
	ip6 daddr @wgset6 meta mark set 0x0000386 counter accept
}

添加路由规则到 /etc/config/network

config route
        option interface 'wg1'
        option target '0.0.0.0/0'
        option table '110'

config route6
        option interface 'wg1'
        option target '::0/0'
        option table '120'

config rule
        option mark '0x3c85'
        option lookup '110'

config rule6
        option mark '0x3c86'
        option lookup '120'
